OEKO-TEX Standard 100: what does the label mean for a buyer?

Main answer

OEKO-TEX STANDARD 100 is a label for textiles tested for harmful substances, with four product classes depending on skin contact, and it covers the tested article only. Verify each certificate with the issuer through its label check, confirm it covers your style, colours and materials, and do not treat it as a mark of quality, durability or fair labour.

What it tests

STANDARD 100 states that every item with the label has passed tests for harmful substances, and that every thread, button and accessory in a certified article has been tested against a list of over 1,000 substances. The more intensive the skin contact, the stricter the requirements. The tests use globally standardised criteria and are done by independent institutes.

The four product classes

Product class 1 covers products for babies and children up to three years. Class 2 covers products with direct skin contact, such as bed linen and underwear. Class 3 covers products without direct skin contact, such as jackets. Class 4 covers home textiles and decoration. Check that the class matches your product, since underwear and sleepwear fall under the class for direct skin contact.

Verifying the label

The label carries a QR code and a certificate number that can be checked in the issuer’s label check. Check that the certificate is valid and who holds it, and what articles and materials it covers. A certificate held by a fabric mill may cover the fabric but not your finished garment, and trims, prints and dyes in your colours may fall outside it.

What it does not prove

It is not a promise about durability, fit, handfeel or ethical working conditions. Use the label only under the licence conditions, and keep wording accurate, such as tested for harmful substances. Ask the supplier for the certificate number and scope document and keep it with the order. See underwear quality and compliance.
